After being locked out of her new house all night, Dr. Caroline Todd is forced to turn up to her new job at the local hospital tired and smelling like a mini-cab after using car freshener as a replacement for deodorant. She soon meets the strange staff, but anaesthetist Dr. Guy Secretan is very welcoming and offers her his spare room for the night while he works a night shift. However after a blocked toilet incident, she soon realises Guy's true motives after he turns up home early and she discovers there isn't actually a spare room.
